Introduction
The Vetus exhaust system components are especially suitable
for use in water-injected exhaust systems.
The maximum continuous operating temperature of the plas-
tic components of the exhaust systems is 70 degrees C
(158-degrees F).
The LSG, LSL and LSS exhaust silencers have a very large
capacity, so that they are exceptionally suitable for use in
systems with extra long exhaust pipes. An extra large capacity
exhaust silencer is of vital importance for a sailing ship, which
will roll and pitch in rough water with the engine off!
The LSG-type exhaust silencer is also fitted with a non-return
valve; this virtually prevents any water entering the exhaust
system. Water entry can be caused by the ship pitching, waves
from aft, or stopping the ship quickly.
• Fit a temperature alarm to warn of excessively hot
exhaust system temperature.
• If the quantity of injected coolant water is reduced to
in order to lower back-pressure in the exhaust system,
check that there is still sufficient water injected when
the engine is ticking-over. This will prevent excess tem-
peratures in the exhaust system.
• Excess temperature can also be the consequence of
insufficient mixing of coolant water with the exhaust
gasses.
In general, good mixing is obtained by a virtually verti-
cally installed exhaust injection bend.
Poor mixing can also occur with an engine on tick-over;
especially when the coolant water injection bend is
installed virtually horizontally.
If necessary, take action. For example; by fitting a water
vortex or a water splitter in the exhaust pipe, to improve
the mixing of coolant water with the exhaust gasses.
With water-injected exhaust systems, fit a hose of suitable
quality.
This hose must be reinforced, resistant to exhaust gasses, high
temperatures (100 degrees C, 212 degrees F) and oil.
Easy flexibility is essential for installation, while the hose must
not collapse when heated.
Vetus exhaust hose fulfils all the above requirements.
The complete VETUS range includes the following hose diam-
eters: 30 mm (1.2"), 40 mm (1.6"), 45 mm (1.8"), 50 mm (2"),
57-mm (2.2"), 60 mm (2.4"), 65 mm (2.6"), 75 mm (3"), 90 mm
(3.5"), 100 mm (4"), 110 mm (4.3"), 125 mm (5"), 150 mm (6"),
200 mm (8"), 250 mm (10") and 300 mm (12").

WARNING
If water enters the engine from the exhaust silencer into
the exhaust system (for example: under sail when the ship
rolls or pitches heavily) this will lead to irreparable dam-
age to the engine.
The overall dimensions drawing shows the maximum
amount of water which can be contained in the exhaust
silencer. Too much water in the silencer can effect engine
starting; drain off this water first. Too much water in the
silencer can be also caused by repeated starting attempts
while the engine refuses to start.
Installation
Installing exhaust silencer LP , LSG, LSL and LSS
Instal the exhaust silencer as vertical as possible. In a sailing
ship, the exhaust silencer should also be installed as close to
midships as possible; this will prevent water flowing from the
silencer to the engine when the ship heels over under sail.
The exhaust silencer 'IN'-connection must always remain below
the level of the exhaust injection bend! Position the silencer
'back-to-front' alongside the engine when there is insufficient
space behind the engine.
During operation, the exhaust silencer will contain water. Its
weight will thus increase considerably, so fit the silencer with
tension straps.
Installing the transom exhaust connection
Fit the transom exhaust connection at such a position that with
the ship fully laden, the transom connection is still at least 5 cm
(2") above the waterline.
In order to install the transom exhaust connection so that it
remains watertight, apply marine adhesive sealant between the
flange of the transom connection, and the transom.
The rubber transom exhaust connection TRCxxR, where xx
stands for the diameters of 40 mm (1.6"), 45 mm (1.8"), 50 mm
(2.0"), 60 mm (2.4"), 75 mm (3.0") and 90 mm (3.5"), requires a
hose connector for fitting the exhaust hose.
The maximum thickness of the transom where the transom
connection is fitted, can be 40 mm (1.6") with this type, with the
exception of the TRC7590R. With these, the maximum transom
thickness is 20 mm (0.8").
With the plastic transom exhaust connection TRCxxPV, xx
stands for diameters of 40 mm (1.6"), 45 mm (1.8"), 50 mm
(2.0") and 60 mm (2.4"), and bronze transom exhaust connec-
tions SPDOORV30 and TRCONxx, xx stands for diameters of 65
mm (2.6"), 75 mm (3.0") and 90 mm (3.5"), the exhaust hose
can be fitted directly, without hose connector.
The maximum thickness of the transom at the place where
the transom connection is fitted, can be 35 mm (1.4") for type
TRCxxPV and TRCxxS, 30 mm (1.2") for type SPDOORV30 and
40 mm (1.6") for type TRCONxx.
